Here is a concise graphic identifying the country's typical teacher. Pay attention to the retirement data as that's something Georgia will have to reckon with in a few years.
At the same time Georgia is seeing a rise in teachers retiring, the state is seeing fewer college students enrolling in teaching training programs.
During the 2007-08 school year, 12,436 students received teaching certificates for the first time, according to the Georgia Professional Standards Commission. Two years later, the total fell to 8,520, and it has remained about the same since.

With that background, here is the chart on the typical U.S. teacher.
